“The USA came to a conclusion that the Russian Federation is violating its commitments within the INF,” he said. In official Washington’s view, this refers to the violation of “commitments not to obtain, not to produce and not to test a ground-launched cruise missile with a range between 500 km and 5.5 thousand km, or not to obtain or produce launching systems for this missile,” the US official specified.

According to the source, the American side considers this issue “as very serious”. “We are trying to discuss it with Russia for quite a while,” the source said.
